Application filed May 8, 1916. Serial No. 98,209. 1

invented certain new and useful Improvel-po ments in Scales, of which the following is a specification.

This invention relatesto weighing machines or scales and particularly to that class of scales which are adapted to be placed on a counter and which serve for indlcatlng not only the weight of the article to be placed on the platform but also serve for computing other data-having relation to the weight with the weight and for indicating the results of said computations.

One of the objectsof the inyention is to provide a scale of thischaracter with an 1n-, dicating devicecomprising a fan tail chart and an indicator or pointer playing over said chart, and to dispose this mdicatmg device in a plane which is perpendicular to the axis of the scale lever or scale levers, in

contradistinction from known fan tail scales, in which the indicating-device, also comprising a pointer and fan tail chart, was arranged in a vertical plane either colnciding with the axis of the scale lever or parallel to the axis of the scale lever. The novel arrangement of disposing the Ian tail chart in a vertical plane perpendicular to the scale lever has the advantage that the operator of the scale as well as the customer on the opposite side of the counter are enabledto read simultaneously the indications with-whichthe free end of the pointer registers, without.

making it necessary for theoperator to change his position This arrangement enables the operator to observe the indications when he places the object to be weighedon the platform, while in known scales the operator had to bend sidewise to observe the indications on the chart. 1 f

Another object of the invention'is to'be seen in the. arrangement of the weight absorbing-element or elements, which in one of the constructions illustrated comprise a mechanism including a plurality of pendulums supported in a point the location of which may be varied with respect to the frame of the scale. The indicator or pointer codperating with the fan tail chart, the lat;

'ter being rigidly mounted in the scale, 1s-

variably located with respect to the frame of the scale, So that an adjustment of the weight absorbing mechanism will not aiiect the zero location of the free end of the inter. Another object'of the scale is to be seen in the novel arrangement of the counter weight for the scale leversand platform. In prior constructions, especially for fan tail scales and also forscales which use a computing drum, the counterweight frequently was mounted directly on the scale, lever near the end of the lever pointing toward the operator, while the weight absorbing mechanism was connected with the scale lever at the free end, the scale lever being fulcrumed between its ends. This arrangement not only necessitated the use of a relatively heavy counterweight for the scale lever and platform, but also placed it readily within reach of the operator, who, either by displacing or mutilating or in any other way tamperingwith the counterweight, was enabled to alter the results of the weighing operation. In the construction described the counterweight for ,the scale levers and platfdrm is connected with the pointer,

which pointer again is aiso connected with the scale levers directly, and is at an end remote from the operator. The axis of the counterweight preferably is located in a vertical plane in. which also the pointer is located, and the weight absorbing mechanism as well as the indicator or pointer may be said to be located in vertical planes perendicular to the axis of the scale levers. It is an object to render this counterweightzad- -mon axis of support, whereby errors which might otherwise be caused by having the scale not on a straight level are automatically eliminated.

It is furthermore an object of the invention to provide flexible connections between the weight absorbing mechanism and the extending from the weight absorbing mechanism are loosely attached.

The invention also contemplates the construction of a weighing mechanism or scale of elements which are constructed principally of stamped sheet metal, in contradis tinction from known scales, wherein scale levers,-pendulums, and other movable parts were constructed as castings, which required,

owing to the sensitiveness with which weighing machines have to be endowed, considerable' machining operations. In the presout scale, not only the scale levels are constructed of stamped sheet metal elements,- but also the pendulum arms, the supports for.

the scale levers, the pointers, the cam elements from which flexible connections exi tend to the scale lever, and the frame. ll-his novel manufacture ofthe weighing. machine greatlyreduces the cost ofmaking the same without having a detrimental effect on the 4 sensitiveness of the device nd without denected with the scale lever istrained serves as a translating device in the scale described.

- Another object of the invention is to pr of the entire combination.

creasingthe'rigidity of the several parts or Another object of the invention is to pro vide a fan tail scale with a longer chart, rendering it thereby possible to perform weighing operation within wide limits, without requiring adjustments of a poise or the like; This'object is accomplished by rendering the pointer movement dependent relation .to' the pointer.

solely upon the. movement of the scale lever, and independent of the deformation or displacement of the'weighing mechanism. For

this purpose the connection between scale lever and indicator includes a motion transs mittmg device, which translates every movement of the scale lever at a predetermined pulley orcircular disk fastened to the indicator and over which a flexible element convide improved ball bearing supports for weight absorbing mechanisms and indicator.

The improved bearing structure renders the axis of the shaft orpivot' to be supported self-locating and actually carries the weight of the shaft on a few halls'in the lower portion of the bearing only;

With these and other objects in view,

Which will become more apparent from the following specification and the claims apended thereto, l have illustrated an emodiment of the invention in the accompany ing drawings, wherein:

The we ghing machine comprises a frame structure, preferably of rectangular configuration, having end walls 1 and side walls 2 provided near the upper and lower edge with inwardly projecting flanges, the bot- Fig. 9 is a perspective view of the equal-' tom of the frame structure being closed by I a plate 3, while the top is closed by a detachable plate at having downwardly extending flanges 5. lhe top plate has a plu- 'rality of apertures through which the sup-' ,portsior the platform project.

The platform 6, comprising a v relnforced plate closed by a cover with downwardly extending circumferential flange 7, also is provided with lugs or feet 8 adapted for insertion into the platform supports described below. The corners of the frame structure may be reinforced by suitable sheet metal parts 9 Welded or in some other way connected with adjoining walls and provided at theirlower ends with beaded extensions 10, which may serve as foot rests for the weighing machine; The weight absorbing mechanism and theindicating device are both located near the rear end of the platform, and are disposed within an extension 11 riveted or in some other Way connected to the frame structure proper. This extension comprises upright members 12 also made of sheet metaland slightly curved'to improve the appearance of the scale, the front of the extension being tition wall 15 transverselyinserted between l the side walls 2 of the frame and a rail 16 part of the pointer.

brackets 21 secu'red to the upright extenslightly ofi'set in its upper part from the partition wall while the lower.part'of said rail is welded or fastened in some other way to the partition wall 15. The uprights 12 projecting from the frame are continued upwardly in the form of diverging extenslons 17, which are connected 'at their upper ends a narrow transverse arc member 18 preferably made of sheet metal and serving.- as a closure for the frame extension as well also as means for attaching holders 19 on which the fan tail shaped chart 20 is secured. This fan tail shaped chart is mounted in the'upper part of the extension, and its ends are supported on angular sions 17. The chart'is rendered visible to the'operator as well as tothe customer on the .op

osite side of the counter through glassp' ates-23, one ofwhich is only shown in Fig; 1 at the front of theextension to The upper portion of the extenrate coverplate 24, which may be detached if it is deslred to have access to the upper That part of the frame structure which surrounds the scale levers and which comprises the end walls 1 and lateral walls 2 is composed of layers of sheet metal plates. By this means therigidity of the frame structure-is greatly enhanced withoutmakiiig it as cumbersome and-heavy as frame structures built up of castings. By suitably interconnecting the various layers of which 13, which may be fastened to the uprights 12 by. screws or some other suitable fastening means.

rigidly mounted these walls are built up as, for instance, by I spot welding, a frame structure may be made which does not require any additional machining after the layers of the walls'have been united. In the construction disclosed (Fig. 10), the walls are composed each of two metal plates, the outer layer consisting I 27, each of them including a lateral wall i and part of each end wall, so that the abutting joints 28 of the metal plates' forming the inner layer are located between the cornersof' the frame structure. The plates of each layer-are in engagement with plates of the other layer on one surface of the same.

In contrast to other fan tail computing scales,

ent instance that the platform is loca'ted the arrangement is made in the presdirectly in front of and'below the indicating scale. A lateral arrangement of the platform with respect to the indicating scale has the disadvantage thatthe attendant placing the load on the platform has to observe a scale which is at his side orat the side of the load to be weighed. If the dial is front of him, however, the placing of the load on the platform and the removal of the same from the platform can be effected without any intermission in the'observation of the scale. Where a large number ofparcels of different weight and of different size have to be weighed in rapid succession, as in large mercantile houses, express companies, post-offices, etc.,'it has been found that by this arrangement a-saving in time of. about thirty per cent. can be had, owing to the -arrangement of'the dial w1th respect to the platform.

The scale levers used in connection with this fan tail computing scale are preferably .made also of sheet metahto combine great rigidity with a reduction in the weight of same, andthey are in general similar. to the scale levers described and claimed in my co pending application, Serial No. 829,903.. The combination of the scale levers includes two arch shaped members sup-ported near their free ends on knife edges and loosely interconnected at their bights by means of over-knife edges 31 and 32 in both of the levers. The upper or main lever 33 is extended'at its forward end, and this extension passes through the suitable opening for this purpose and car.-

a link 30 hung rie'sradjustably at'its front afurther extenpartition wall 15,1which has a sion or nose iron 34. The support of'the.

scale levers with respect to the frame is effected by means of bars transversely mount- I ed in the frame and rigidlyfas'tened in the lateral walls of the same.

flanges of the channel bars are extended upwardly at suitable distance from the side walls of the casing so that short uprights 37 project from the top edge of the bars (Fig. 12). A threaded pin 38 extends through both of these opposing projections," and 1s held thereinby means of a head fastened to one end of the pin, while the other end carries a nut whereby the pinmay be securely locked in place. small bracketor clip 39, preferably also made of sheet metal,

comprises a back portion having an indentation L0 and two leg portions, the distance between the two leg portions being equal to the distance between the upright flanges 3-7 of the bar. This clip, being provided with registering holes in the legsthrough which the 30 pin 38 extends, is thereby rotatably mounted with respect to the transverse bar 35. The reduced edge of the knife 41 supporting a leg of the scale lever is resting on the indcntation of the clip so that the support of this scale lever will automatically adjust itself to remain at a level even though the scale may be placed on a platen or platform without having all of the foot portions in exactly the same level.

The knife edge all projects through the walls of the scale lever (Fig. 11), and this projecting end is guarded by a clip 42 having'an angular extension 43, which is riveted or fastened in some other way to the channel bar and projects from said channel .bar upwardly into. prom'mity of the knife edge. A small guard clip 44: is alsd fastened to the other side of the scale lever by rivets or the like.

-..Thenose iron 34-, adjustably secured to the extension 45, which projects from the central portion of the main, lever 33, and

which-passes through the partition wall 15,

has .a plurality of prongs. One of these prongs 425 is located in a vertical plane passing through the central axis of the scale lever, while another prong 4-6, preferably longer than the ii'rst named prong, is located in a vertical plane which does not go through the axis ofthe'scale' lever and which projects beyond the end of the first named prong 45. The first named prong l5" serves for connecting the scale levers with the weight absorbing mechanism, while the second,-'or longer, prong 46 serves for connecting the scale levers with the indicating device so that the weight absorbing mechanism and the indicating device are independently connectedwlth the extension of the scale levers.

011c form'of the weight absorbing mech- 'anism, as descrlbed in connection with 1 1g.

4, comprises a plurality of pendulums. The weight absorbing mechanism is supported from the transverse member i l, which connects the upright extensions 12 on the frame.

A sleeve 50 having a central bore is riveted at its upper end or rigidly fastened in some other suitable way to the transverse member 14c projecting downwardly therefrom, and isadapted to receive slidably the stem 51 of a yoke indicated'as a Whole at 52, in which the weight absorbing mechanism is supported. The stem has circular cross-section to fit into the sleeve, and is prevented from rotating within the sleeve by means of a set-screw 52, which extends through a longitudinal slot 53 in the sleeve 50 entering a threaded aperture in the stem.

' An adjustment in vertical direction of the yoke may be effected by means of a screw 5% accessible from the upper end of sleeve 50 and engaging a bore 55 having internal thread in the stem 51. By rotation of the screw 54 the stem 51 Will be drawn upwardly into the sleeve or may be" lowered with respect to the transverse member 14, so that the weight absorbing mechanism can be adjusted with respect to the frame or to the scale levers without affecting in any way the indicating device, which is not supported in the yoke 52. The foot end of the stem 51 is provided with lateral arms 56 having angular extensions which are rigidly connected with the upper ends of arms The lower ends of the vertical arms 57 are angularly deflected so as to converge downwardly, as indicated at 58, and at their free ends they areunlted with a central vertical tongue 59,

which serves as a support for a bearing structure holding journal pins of the pendulums. This central tongue 59 extends from the point of connection between the deflected portions 58 upwardly toward the lower sur-.

face of the lateral arms '56, with which the stem 51 is rigidly'connected.

The depending arms 57 are each provided with an apertureserving for the reception of a bearing member 60, which is threaded externally so as to be adjustable with respect to the" arms. This bearing member has a central recess 61 in which an annular groove 62 is located, and this groove serves as a ball race for the bearing balls "63, which are in engagement with the journal pin 64 projecting from one surface of the pendulutns. lit

will be'seen that by this construction the pendulum is supported in aball hearing which can readilyloe removed from the supporting brackct or yoke and whlch also may be-adjusted in axialdirection b rotation of I through the tongue" 59 and through the'cen shoulder 75, may be located in a plane with i the marginal portions of the arm 75.

An extensionv at the opposlte end of and" in axial alinement with the journal pin 64' projects from the other surface of the pendulum and finds a similar support in a ring 66 inserted into the central tongue 59 of the yoke, which tongue has a slot 59' open at the upper end of the tongue, so that the ring 66 may be lowered into the slot. The ring 66 has holding flanges 67 at both sides of said central ton ue. This bearin ring also is provided with internal annu a grooves 62 on each side adapted for the reception of ball bearings 63, and it is secured in position by means of a pin 63 driven transversely tral outer annular groove 67' between the The entire yoke, with exception of the parts which are to be manufactured on. a lathe, is made of stamped sheet metal and the several parts are held together by riveting, weldingfdr'in some other suitable way. The journal pins 64-and 6'5 form-axial exten sions of a short rod '70, substantially of circular cross-section, extending through the. upper portion of .each pendulum; this rod has a threaded portion at 71 and a circular portion'or shoulder at 7 1 on which the plate 7 2 of the cam member is resting, and this plate may be forced against the circular ex tension 73 at the upper end of each pendulum arm by the nut 74. The extension 73 of the arm rests on a non-circular shoulder 7 5 forming part of the short rod 70, and iSf forced by the nut 74 against a larger circular flange 7 5", having a central depresslon or recess 76 into which a holding flange 67 of the ring 66 projects. By reference to Fig. 5

it will be noted that the ends of the pivot extensions 65 are rounded and are in abutment at their'central portions, so that axial friction is reduced to a minimum.

Each pendulum comprises an arm 7 5, preferably made of sheet metal and having a circular extension 73 at the upper end, and a similar or lar er circular extension 6 at the lower end. metal, may be reinforced by being bent 1n cross-section to provide a corrugated rib 76,

which 'is offset from the marginal portions of the arm 75. The circular extension 73,

through which the shortrod 7 O extends and -which for this purpose has a non-circular aperture corresponding to the non-circular lower circular extension 76 on the arm carries a circular casing 77, 111 WllICl1 d1SkS of lead (not shown) or other heavy material are concentrically secured by means of a fastening screw 78..

From the above description it will be seenhe arm 75, which is of sheet.

The plane of the central tongue 59 in'the supporting. yoke for the eredas defining the plane of the same, and 1t Wlll therefore 'b'e'funderstood that this weight absorbing mechanism is located in a and integral with said circular plate 72 on each cam member is an eccentric cam portion 82 having a flange 83, which is bent at right angles to the plane of the circular port-ion 81. Near the upper" end of theof steel bands 84, which are fastened by rivets 85 or the like. The lower ends of the flexible steel bands are provided with a weight absorbing mechanism may be-oonsidcurved eccentric flange 83flexible connec 'tions are' secured, preferably in the form clips 86, whereby the cam members may be secured to the lever system,- as will be described below.-

- The circular plates 72 of the cam members 80 are clamped againstthe circular extensions 73 of the pendulums by the nuts 74;

they are pressed against .those surfaces of the pendulum plates 73 which are directed away from the common bearing ring 66.

The angular flanges 83, however of these cam members are both bent. into direction toward the central plane going through the tongue 59, and they are sufiiciently'broad so that the flexible'connections 84 secured tothese'flanges lie in one common plane, even though the circular plates 81 are on the opposite outer surfaces of the'pendulum disks 73. Each of the circular plates 81 furthermore is providedwith a tongue 87 projecting in the planeofsaid circular plate in-a direction substantially opposite to the direction of that pQrtion 'of the plate which carries theflange 83-. These tongues 87 rough can aperture 88 in the 'c'orruga portion or rib of the pendulum a d ente into, the. recess87. ,of a locking platej88,"iwhich is "secured on the rear surface of each-pendulum arm by means of holding screws 89. ,Bythis means the location 'of each cam member may be posiv tively fixed to bring 'the hump or middle part of the flange of the cam member into rectly, This locking, plate is thenpermanently secured to the pendulum arm and the cam member will thereby be retained 1n proper position. A rotation of the cam member with respect to the circular exten' sion '73 of the pendulum is prevented even in the continued use of the weighing machine, and the occurrence of errors in the weighing operations which might otherwise be introduced by an angular movement of said cam members with respect to said circular extensions is avoided.

lhe cam members 80,'securely connected with, but detachable from the pendulum 75,

are also made of sheet metal, contrary to the construction of similar cams, which 'usually' weremade as an .integral casting withthe pendulum or as a separate casting.

Owing to the construction of the cani member ofstamped sheet metal, the-curvature of the cam flange 83 may be adjusted so as to obtain a predetermined angular deflection of the scale levers with each uniform increase of weight on the scale platform. lin

weighing machines inwhichthis cam member.was formed of a casting, inequalities in the cam surface, which again caused unequal defiectionsof the scale levers with equal increases in weight on the platform,.could only be remedied by grinding off those portions of the surface which showed pro ections or humps where these humps were detrimental to the exact weighing; and an inexact cam surface, where-the inexactness was caused by the opposite defect (a slight indentation),

could only be corrected by grinding off the entire camv surface, excepting that portion which caused the inexactness. If, in the present invention, a similar defect should be present in the cam flange 83, it is possible to remedy the same by bending the sheet dents, shocks, or the like as they may occur I metal flange outwardly, that is'by raising the indented portion, orby some other suitable deformation vof said flange caused by the application of strong pliers. A deformation of the adjusted cam fiangeby acciin every day weighing operations, is hardly possible, as the cam plate is made of suffioiently heavy stock towithstand these accidental strains. 7 l

In order to connect the weight absorbing mechanism, comprisingin the embodiment described above twopendulum arms and two cam members, with the scale lever 33, an

of the pendulums, therefore,

need am.

intermediary member, in the form of an equalizer bar90, is provided. The equalizer bar comprises a horizontal portion 91 havaxial shorter prong of the nose iron projects.

The connection between the nose iron and the equalizer bar is rendered readily detachable, as a pointed screw 95 securely held by,

means of a lock nut or the like in the front portion of thesaid prong engages with its point a central indentation 96 in the head 97, of a screw 98 which is secured to the bottom member of they stirrup 93. This bolt 98 extends through..the bottom portion of the-stirrup projection"93 and is held in place by'a nut 97, tightened up against the lower edge of the stirrupf The. equalizer bar 190, like the other main parts of the weighing machine, is made of a blank stamped sheet metal-which is .bent centrally so as; to present two depending flanges 90'- separated from each other by a slight interspace. Clips 98 are-secured to the upper and lower edge of the bottom member on.

the stirrup and serve as washers for the head 9? and for the nut 97 of the bolt, receiving the bearing point of the nose ironscrew .96.

Owing to the weights 7-7 on the pendulums, the equalizing. bar 90will be drawn upwardly continuously, as theends of this equalizing bar are connected by thesteel bands 84 to the cam flanges 83; The weight has a tendency to force the head 97 into engagement with the needle point on the screw If it is desired todetach the equalizer bar from the nose iron,'this bar is forced downwardly to a'slight extent with respect to the nose iron, whereby the engagement between the head 97 and the point of the screw 95 is interrupted- This downward movement ofthe equalizer bar with respect to the nose iron is efi'ected by a small cam 100 freely rota of the equalizing bar and preferably, disposed in the small interspace between the,

= two flange portions-of the equalizer bar 90 The cam 100 comprises a-portion 102 conpivot l0l, and projecting centric with its slightly above the topedg'e of the bar; this concentric projecting portion is integral with. an-eccentric portion 102 projecting downwardly into engagement with the top end of the screw 95 on the nose iron. -The cam 100 is mounted loosely so that it is gravity-controlled and so that the heavier eccentric portion will ordinarily be directed downwardly,and by slightly rotating the knurled projecting portion 1102, the eccentric portion 102 will'be forced out of engagement with the top surface of'the screw '95.

After these two members are disengaged from each other, a slight downward pressure on the equalizer bar '90, overcoming the weight of the pendulum system 77, and a slight rearward movement will be sufliclent I to remove the equalizer bar from its connection with the nose iron.

It should be noted that in spite of the duplicate arrangement of pendulums only one point. of engagement absorbing mechanism with the scale lever system is used, this point of engagement beend of the screw 95 ing where the pointed It is obvious that the rests on the head 97 extent to which the pointed end of the screw spect to the fulcrum of the pendulums, and

owing to the rigid connection of the eccentric cam elements with the pendulums, a

swinging movement is imparted to the lattor. Owing to the relatively large leverage,

. between the weights of the pendulums and the cam elements, a relatively large force must be used in pressing on 'the scale levers for imparting swlnging movement to the free and weighted ends oilthetwo pendu lums. The amplitude of theswinging movement willbe at different conditions in different proportion to the weight acting on the scale levers without-being, in any way, dependent upon the distance between the fulcrum of the p'endul ums and that point on which-the scale levers engage the system. of

screw 60 extends identical-with tli be member 60, which serves for sup biting the pendulum arm in the yoke 52 eaxls oil this screw is located in the center of the circle defined by one of the edges of the indicating chart or dial. A similar bearing member 60 also extends through the rear .face of the bridge or transverse member 111, and both of these hearings are provided with ball races 62 for hearing balls 63 to support the journal pin 113 of the pointer1110.

Thebearingsshow the advantage that the shafts of the pointer and pendulums respectively rest directly proper selection of the size of the balls each shaft end will rest on the two balls occupying the lowermost space in the ball race. The other balls in the samerace simplyact as spacers, and while in slight frictionalrolling contact with the surface of the shaft, (10' not serve for supporting the weight of the same. A binding of the shaft in the bearing is thereby avoided, the more so as the axial thrust is taken up in one point; namely, the needle point of pointer shaft resting against the bottom surface of' the bearing screw 60, or by the contact points of the two curved-abutting'end surfaces of the ,shafts for the pendulums.

The pointer consists'of a circular disk 116, from which extends in one direction an integral arm 116' tion, the width ally reduced in disk toward the free end of the arm. lo the of the channel being gradufree end of the arm' a bifurcated indicator clip 117 is secured-by rivets or the like, this clip being arranged so that its prongs are one on each side of the dial near the lower edge of the same. lln opposite'direction from the channel shaped arm. the pointer carries a counterweight 118, which is preferably integral withthe disk 116 and which may have any suitableshape.- Hence, the circular support 11 6 for the pointer, the arm lllfii, and the counterweight 118 are prefer- 5' metal to-reduce the weight as well as to fa- .cilitate the manufacture of this element. A

right angles from the plane pulley 120. -One-h'alf flanged circular disk or pulley 120 'is centrally secured to the circular central portion of the pointer, flexible connection 120 is secured by rivets or screws to the flange-121, projecting at of the disk or of this flexible tension element 120 extend's'downwardly and carries at its free end a stirrup 122, into which A the free end of the lateral prong 34 of the mam lever nose iron is introduced.

It will be seen from the above that the in- I d1cating device,

comprising the indicator arm 110 and the curved chart orindicator dial, is located in a plane plane in which the weight a sorbing mechanism is located and near the same end of the platform near which. said-last named mechanism is disposed.

on the balls, and with' of channel shaped cross-secj direction from the circular made of one piece of stamped sheet- -increase of the counterweight,

and a steel band or other arallel to they .pounds is placed on the rea ers lever acts as a translating device for the indicator. By selecting a suitable diameter for the pulley, to which the steel band isattached, the pointer 110 may be deflected more or less at the same movement of the prong 34 in vertical direction. If the pulley is very small, a downward movement of the prong exerting a pull on the steel band trained about the pulley will cause a larger angular movement of said pulley, as if the same would be larger. This angular or rotary inbjvement ofthe pulley will be in direct proportidhfhowever, to the'movement of the prong of the lever, so that the deflection of the pointer must be proportional to any increase in weight on the platform, whereby a strict uniformdivision of the indicator chart is'rendered possible.

The other end (of the'flexible element, said element being fastened to the circular flange 121 of the pulley, carries a clip or hook 124, which supports a'counter-weight 125, preferably COII SISlLiDgof a cup-shaped member containing disks 125' of lead or similar heavymater'ial and being closed at its upper end by a screw-cap 126, which carries a transverse pin 126 to receive the hook 124: on the flexible tension element or steel band 120.

Contrary to the ordinary construction of scales, and especially of fan'tail scales, the counterweight for the scale levers is herein located at the end remote from the operator, so that the operator is not tempted to mutilate the counterweight or to change the position of the same; furthermore the counterweight, being located at a relatively large distance from the support of the scale levers,

utilizes a long lelverage, thus reducing the size of the counterweight considerably as compared with weights serving the same purpose in other scales.

lit will be seen that a reduction or an resulting from adding or removing one of the disks in the same, will alter the normal height-or position of the scale levers. This alteration will then lead to'an alteration in the relative position of the cam members connectedwith the pendulums. If upon tes ing the scale it should be come evident that the shape of the operative cam surface'of these members is correct, but that the hump of this surface (which becomes of importance in weighing objects having a weightmidway between the minimum and maximum weight for which the scale is intended; as, for instance, when in a scale hav-.

lnga maximum weighing capacity of fifty pounds an article platform) is not in proper position, it will only be necessary to alter. the counterweight connected with the Weighing twenty-five iac tion with the pivot of the pendulums.

The support of the shaft for the pointer,

' and its connection with the translating de-' vice, is similar to the connection of the support of the shaft for the pendulumsand its connection with the cam members.

The indicator shaft 160 is pointed at both ends, as shown at 161 and 162, and rests with these points against the bottom walls of the ballbearing screws 60, secured in adjustable positions in the rear transverse member 111 and bracket 112 respectively by nuts 163. The pointer shaft the central circular disk 116, the latter being provided with a non-circular opening whereby it rests on a corresponding non-circular shaft 160.

clip The free end of the flexible steel band connected with the translating device carries a stirrup 122', the bottom plate of-which has a depression 171 to receive the pointed end. ofa screw 172 secured in the prong 34 r of the scale lever and adjustabletherein by means of a nut 173. This engagement between the stirrup late and the screw. is normally maintaine owing to the connection of the variable counterweight, also secured to the translatingdevice by the steel band.

The invention also provides a novel support for the platform 6 on the scale levers. The scale levers are provided near their supporting points 35 with lmife edges 130' extending through both of the walls of the channel shaped levers and carrying thereon links 131, which extend downwardly. -A 260 of sheet man isinsertedbetween the operative edge of the knife edge 130 and the link 131 straddling said knife edge, so as to facilitate the attachment of said linkand to protect the link against excessive wear caused by engagement of the knife edges. The links 131 also carry knife edges 133 near their lower ends, and these knife edges are rigidly connected with inverted stirrups 13 1 passing through openings in i the scale levers. The upper ends of said stirrups have an opening 135 shaped in acis enlarged at 164 ,to re-. ceive a circular washer 165, which is secured to cordance with the cross section of- 8 de endingfrom the platform 6, so that t eplat orni will be -supported by thev inverted stirrups 134 from the scale levers; when the lugs are inserted into the openings 135; The stirrups being suspended from the knife edges 130, it is obvious thatthe' have flanges 138,- which. are united by welding, the central portion of these stamped sheet metal parts being ofi'set. so as to provide room for the insertion of the links 131, be-

are preferably constructed each of two stamped sheet metal parts having lateral tween the lower portions 136 of the sheet metal members. v After the lugs have been inserted into the apertures 135 of the upper portions 137, they may be held therein by pins 139, which are driven transversely through the upper portion 137 and through the lug 8, the latter being provided with a suitable aperture for this purpose.

Where it is desired to use a spring as weight absorbing mechanism, the pendulum construction described above may be replaced by the spring support and spring shown in Fig. 22. This spring support comprises a stem 51 similar to the stem 51, which is used in connection with the yoke 52 for supporting the pendulum mechanism,

this stem mav be lowered or raised with respect to the frame by the screw 54 exactly as described in connection with the pendulum weight absorbing'mechanism.

A central lug 200 pro ects downwardly from the lower end of the stem'51', and a pin passing through that lug supports the two prongs 202 of a, small clip 203, a transverse element 204 of this clip' is inserted between two of the upper .end windings of a weight absorbing spring 205, the friction of the windings on the transverse members securely holding the spring in connection with the clip. In a similar Way two windings of the spring 205, near the lower end of the tapped-bore of the clip 206, and the lower portion is provided with a saw kerf to're ceive the steel band 210. After this band has been inserted into the kerf, it may be secured therein by driv ng riv'ets through the inserted portion and through the lower end of the stem 208, closing at the same time the width of the saw kerf to the thick-- ness of the steel band. A small clip 211 is also riveted or secured in some other suitable way to the free end of the steel band 210,

. and this clip, has two projecting lugs 212 separated from each other by a smallinterspace into which the upper portion of a cam 212 may be inserted. The projecting lugs on the clip and the upper end of the cam are provided with bores which are in register when the parts are assembled, and

a pin may then be driven through the lugs and the projection of the cam, whereby the cam is united with the weight absorbing mechanism comprising spring and flexible band.

The cam is mounted in a link of anon-- struction similar to the constrnction of the equalizer bar referred to above, this link, however,,being free of any lateral arms, as this spring weight absorbing mechanism is in direct connection with the central por-- two flanges which extend downwardly, a

small screw 214C, having a square head with a central indentation, as shown at 214, and

Y held in thesaid interspace by the nut 215.

lhe opening of the-stirrup link 213 serves for the same purpose as the opening in the" "equalizing bar; namely, to receive the projecting end of the prong on the nose iron 34 to which a pointed screw is fastened, said screw entering when the parts are in opera- I tive position in the central indentation of the head. I

In order to adjust this weight-absorbing mechanism to the proper length between stem 51' and clip 211 without stretching or in some other way tensioning the scale spring 205, it is only necessary to rotate the stem 208 somewhat in the lower'central clip, as this rotatable stem isin threadedengagement with the bore in the lower clip. After. the parts have been adjusted to their proper length, a lock nut 217, fastened on the threadedpart of the stem 208, is tightened up against the lower surface of the clip 206, and the parts are then-in proper adjustment.

- With the intention to improve the appearance of theweight absorbing device, and

especially with the intention of protecting the spring against the influence of the atmosphere and of fluctuations-in temperature, an air insulated acket is provided for the same,

tire scale inclosed in a casing does not presaid jacket comprising two concentric tubings 220 [and 221' separated from each other by a suitable intersp'ace, the inner tubing being large enough to receive the spring 205.

At the bottom the two'tu'bings areclosed by a disk- 215, having a slot 219through which the lower end of the band 210 and connecting clip 211 projects, and the air insulating jacket thus formed is fastened to the stem 51 by a plurality of screws 223, which go 7 through the upper end of the outer tubing into a collar 222 forming part of the stem 51, fitted -to the inner diameter of the outer tubing, said collar also being preferablyin engagement with the upper edge of the inner drawing, is also independent of the weight absorbing mechanism, and is located in a plane parallel to a vertical plane going through the axis of the spring and perpendicular to the longitudinal axis of the main lever In this modification, therefore, the

weight absorbing mechanism'and the indieating device also may be, arranged at the same end of the platform and preferably at that end which is. directed away from the operator. r a

A braking device for the movement of the main lever is provided in the form of a dash pot, the bottom of which is securely fastened to the bottom plate of the frame structure, as shown at 230; said dash pot containing a piston 231, which is flexibly connected by means of the rod 232 with a transverse pin 233 pasing-through the nose iron of the main lever. The dash pot is closed on top by means of a screw-cap 234:, having an aperture to permit the passage of the piston rod therethrough. 1 j

Shoeks or excessive strains under which the weighing mechanism may be placed when an article, exceeding in weight the maximum weight for j which the scale is intended, is placed-on the platform, will be absorbed or taken up by yielding stop 240,

vcomprising a pin 241 mounted at the free end of a strongspring 24:2, the lower end of which is securedin the front channelwhich carries the scale lover. The spring 242 preferably is selected of a strength large enough to absorb a weight twice as large as the scale is intended for. If the maximum capacity of the-scale should be fifty pounds,- an additional fifty pounds may be placed on the platform'witho'ut subjecting the elements connected with the main lever to an excessive strain, as the excessive load is takenup by the spring 242. .1 7

It will be seen from the above that the ensent any parts which would provide any temptation for the operator to move or adjust the same. The scale may be carefully v tested and adjusted in the shop and may then be sent out to the customer, who will not even be compelled to use extreme efforts in placing the scale on absolutely straight,

horizontal level. All of the'movableparts,

including the bearings, are centrally located,

ment of the weight absorbing anda slight tilting of the scale will not affect the accuracy of theweighing operations. It will be seen that, owing tothe interposition of a translatin' device between the indicating device an the scale lever, the dial or chart can be made considerably longer-than in other fan tail scales, and the divisions on said chart can be uniform over the entire range. It will also be seen that the adjustment of the indicating device can be ren dered entirely independent of the adjustmechanism, as the support for the weight a orbin mechanism is located at a point difier ent; om the su port'of the indicator. v

ith reference to Fig.- 21 it will be noted that the knife edge 130, which serves for supporting the link 131, is protected by a small clip straddling the same,

so that the link 131 while loosely in connection with the operative edge of the knife edge willnot cause ing thesupp'ortofsaid ments, and indicating means-movably con- 7 destruction ofthe same at premature time. This clip 260 restin on the knife edge 130 is at its ointed en 3 in engagement with a check clip 261 which has vertical wall portions 262 and horizontal ortions in engagement with the walls of t e scale lever. By means of this check clip 261 the smaller clip 260 is held against lateral motion, and the freely suspen I claim: a a 1.
